Abstract
A mirror is fixed at the front of a mirror holder constituting a moving body. First and second coils are attached on the outer circumferential surface of the mirror holder at both sides of a plane passing through the center of gravity of the moving body and parallel to the surface of the mirror. The moving body is rotatably supported by springs so that a rotation axis and another rotation axis orthogonal thereto pass through the center of gravity. Magnets are fixed to a stationary magnet holder to lie at the right and the left sides of the first coil and the upper and lower sides of the second coil. The centers of torque acting on the first and second coils when driving current is applied to the first and second coils are set in the vicinity of the center of gravity and the supporting point of the springs.
